To all whom t may concern:

Be it known that I, MILTON Manners, a citizen of the United States, andresident of Detroit, Wayne county, State of Michigan, have inventedcertain new and useful- Improvements in Hydrocarbon-Motors, of which thefollowing is a" specification.

This invention relates to hydrocarbon motors and particularly tomulti-cylinder motors. Une embbdiment of the invention is shown andincludes a six cylinder motor inwhich there are two block castings ofthree cylinders each mounted on a suitable base or crank case. K

One of the objects of the invention is to produce a multi-,cylindermotor of clean external appearance, andone in which various parts olithe motorare housed or inolosed. i 4

Another object og the invention is to illiprove the water circulationsystem through the various jackets of the motor, carbureter,etc.

Anotherobject ol. the invention is to improve the support and housing ofthe valve operating, shatt. y y

A11ther.object of the invention is to improve 1the valve and valveoperating Inecl1a msm.

ther objects of the invention will ap-y pear from the followingdescription taken in connection with the drawings which form a part ofthis specification, and in which1 lFigure 1 is a side elevation andvertical sectional view oir' a' motor, embodying this invention; f

Fig. Z is an elevation of the `valve shaft supporting'piece which alocomprisesthe .intake header and, wire bruising?V with the cover securedthereto; Fig. 8 is a View of said valve supporting piece.

In the yernbodiinent of the invention reverse side' ot' 'W shown herein,the motor comprises six cylinders cast 1n two blocks of 'three cylinderseach. llt willbe understood that a lesser or linders may be ciners maybe otherwise the crank pins 17 of the crank shaft 18 which is mounted insuitable bearings 19 in the crank case 10. l

The upper ends of each (it the cylinders 14 is somewhat contracted, asshown particularly above the upper limit of 'travel of the piston 15.This contracted part of the cylinder is double walled and 1s of outwardcylindrical form and constitutes a waterjacketed head for thc cylinder.ln it are arranged suitable inlet ports 22 and exhaust ports 23,preferably arranged inlgthe same zone and ,bth o f which'are ada to becontrolled by a cylindrical or sleeve valve 24. For feet lit for thevalve 24, it is sometimes desirable to place a linin sleeve or collar 25patenten apr.. saisi.

inV Figs. 1 and 5, forming a domeshiiped combustion space 20immediatelyy Gli' the purpose of getting a more peron the outside of thecad 21, said liningon sleeve of course being provided with inletI andexhaust ports alinin with the ports 22 and 23 formed in the cy inderhead.

The cylinder head 21 is also provided with a central depression orcavity 26 in,

which a spark plug27 is suitably arranged in communication with theinterior of the i cylinder or combustion space 2 0. The central terminal28 'of the spark plu extends above the top of thecylinder head and thecavityv 26m is closed by atsuitbble cap 29 ol insulating,material j Itwill beseen that the cylinders Ml are water-jacketed as at' 30 and thisjacketing space continuesup into the head 21. Water is supplied forcooling purposes by a pump 31 operated by suitable connections fronfthemotor cra-nk shaft 19, through pipes 32 and,

" castings 13, as shown particularly in Fig.

33, to the lower part of each ofthe cylinder 2. There is a water outletfrom each of the heads 21 as shown at 34 in Fig. 5, and

to all of these outlets is connected a pipe 35' which runs across thetop of the c inders Vand connects with a suitable radiator, not shown inthe drawings. 'Ofcourse it will be `understood that the pum 31 draws thewater from the bottom o thev radiator through pipe 36 shown in Fig. 2,thus causing a constant circulation of water through the motorwater-jackets' and the radiator.

Each of the cylinder heads 21 is surrounded by a headpiece 37 removablysecured to vthe cylinder as by bolts 37', vwhich 'head "ieee isdouble-walled to form a Water jacket as shown in the various figures,and these head pieces l37 are substantially square exteriorly, so thatthey will t closely t0- gether on the tops of the cylinders and form 4acompact arrangement thereon.

1 the four 'stroke cycleprinciple.

It will be understood that a' suitable cylindrical space is leftbetweenthe exterior of each of the cylinder heads 21 and the interiorwalls of the head lpieces 37, to form la valve chamber inwhich the valve24 operates. As shown herein, this valve is rotated by suitablemechanism to` control the inlet and exhaust ports. The valve 24 isformedwith one or two ports 38 which are adapted short sections of pipe 39(see Fig. 2), and a pipe40 leads from the pipe 33 to the lower part ofthe-head piece 37 of' cylinder numberll, and an an outlet pipe 41leadsfrom the upper part of the head piece 37 of cylinder number' 6 tothe" water-jacketedA part 42 of the carbureter 43.` Also a pipe 44 leadsfrom the lower. part of .the carbureter water jacket to the water jacketof one of the cylinder castings' 13. As above suggested, laI lmodifiedform of this system comprises the elimination of pipes 44 'and 40- andthe substitution therefor .of

la pipe 45 shown in dotted lines in Fig. 2 as extending'from thelower-part of.the carbureter jacket 42 to the head piece 37 of cylindernumber 1. By the latter arrangement, there would be a constantcirculation of water serially` through the variou's head pieces, andfrom -head piece number 6 through the pipe 41 and carbureter waterjacket 42 and from there throu hfthe ipe 45 back again to head Vpiecenum r1. hus

the cooling action of the carbureter 43 would act as a radiator for theheated water from the head pieces, while on the other hand the hot waterpassing throughthe water jacket of the carbureter would assistmaterially in vaporization of the gasolene. With the system shown infulllines in Fig. 2,'the water pumped into the pipe 33 would be dividedtherein, part of itgoing to the rear cylinder casting 13, part of it tothe front cylinder 13 and some of it to the head pieces `37 through thepipe 40. Of coursethe heat in the cylinder water jackets and the headpieces, would materially aid in the'circulation of the water throughthem. A

For the purpose of rotating 'the valves 24, a valve operating shaft 46isprovided j. and is arranged longitudinally of the motor,

adjacent each of the valves. -The valves 24 have teeth 47 eut intdthempreferably within their curCumerence, thus formin worm gears on thevalves, and the valve-s aft 46 is provided with a series ofworm wheels48 adapted to mesh with the gears of the varions valves.

Inthe drawings, a memberA 49 which is partly in the form of a casing, ispro- 'vided with suitable bearings '50 for the valve shaft 46. Thisarrangement of the bearings` for the lvalve operating shaft insurestheir. being in proper. alinement, and the shaft may be assembled in itsbearings -before the member 49 is mounted upon the motor. Figs. 7 and 8illustrate the member'49 some what in detail,and upon reference theretoand to Figs. 1, 2, 3, 5, and 6, it will be seen y. that lthe member 49is adapted to extend .lengthwise of the motor and to be removablysecured to each of the head pieces 37 as by bolts 51. It will 'also beseen that the member 49 is formed'with an elongated opening 52 whichexposes the valve oper ating mechanismv when the member is in place' onthe motor, and this o ening 52 is adapted to be closed by a suitalecover 53,

,secured thereon as by screws or bolts 54.

Suitable meansvare provided for operating thevalve operating shaft fromthe motor` crank shaft 19, and in the present embodiment this meanscomprises a vertical shaft 55 shown in sections which areconnectedbyuni'versal joints 56. A tubular housing?? surrounds thevertical shaft and is suita ly connected at its upper end to the cover53 as at 58, and'at its lower end to the crank case as at 59. The lowerpart of the vertical shaft 55 .is mounted in suitable bearings 60 andtheupper partis-mounted 'in suitable bearings 61. A worm gear 62 0n thevertical shaft 55 meshes with a worm gear 63 on the motor crank shaft19, thus forming a driving connection between thc motor crank shaft andthe vertical shaft, and

a worm ear 64 at the upper ,end of the vertical aft 55, meshes with awormx-gear meshes 55 at the center of the valve operating shaft 46, thusforming'a. driving eonzierion with the latter.

Upon reference to I*`igs. l and 5 to 8it will be seen that the member 4)has a cored out portion or passage 66 4which is adapted to form themotor intake pipe or header. This pipe or passage (S6 has an opening 67for each of the head pieces 37 which lpermits the passage of gases fromthe intake pipe to and through ports 68 forn'ied in each of the headpieces 37 in alinement with the intake port 22 in the heads 2l. At thecentral part of the passage. (36, is an opening 69 which communicatesthrough a short pipe section 7 0 with Athe interior of the earbureter 43hereinabove described. This arrange- -`ment. is particularly well shownin 'Figs'. 4 and 6 and it will be seen that the carbureter 43 isarranged substantially at the center ot' the motor between the two blockcastings 13 and directly inwardly of the 57 for the vertical shaft 55.

The member 49 has also formed as an integral part thereof, a. casing orhousing 7.1 which is open. along one side and closed by a removablecover 72. Within this housing are suitably arrangcd'the irnition wires73 ot' the motoigand switches 4 lead from the various wires to theterminals 28 ot' the spark plugs 27 hereinabove described. Theseswitches 74 are preferably pivotally mountA ed upon the covers 72 asshown in the drawings.

From the above it will be seen that the member 49 extends lengthwise ofthe motor and forms a housing for the valve shaft and is also providedwith channels or housings forming respectively the motor` intake pipeand the casing for the .ignitionwires.

On the side of the motor opposite-.the ports (S8, the head pieces 37 areformed with exhaust ports 75, and an exhaust pipe 76 is arrangedlengthwise of the motor and connected to the head pieces 87 so that itsinterior counnunicates with each oi"y said ports 7 5. ports 7 5 are inalinement with 23 in the heads 21.

It will be further understood that the valves 24 are rotated orotherwise suitably operated through the gearing hereinabove described,to open and close the inlet and lexhaust ports exhaust ports 22 and 23,Vso that the intake port only will be open on'the first down stroke ofthe piston, both ports will be closed on'theup stroke' following, bothports Will ,be closed on the next downward or firing stroke of thepiston, and theY exhaust port only open on the following,r upward orexhaust stroke thereof. In Iother words, the valves 24 will be operatedin suitable rela-- tion to each other,.so that each of the cylinderswill hre on principle.,

tubular housing lt will be understood that the the four stroke cycle ltwill be further understood that various modifications of the embodimentot' the invention herein shown may be made without departing from thespiritJ or scope of the invention.
